    Not that I in any way know it all on this subject... but I only run my boats once a month, so I put my batteries in storage mode. They are also in storage mode during the long winter in Michigan which causes 4 to 5 months of non-fun.
    Have fun with that....

      Well after doing some searching it seems like some people storage charge and some don't. I'm in the storage charge camp myself. Let me explain why.

      Well first off I had a gens ace 2s battery I used for my recovery that I cared nothing for, so I left it fully charged at all times. It never puffed. That's just a regular voltage lipo. Now. I've had a few high voltage batteries puff just sitting if I left them fully charged. It doesn't happen if I leave the voltage below 4.2 instead of full voltage...seems like anyway. I must note, I store them in my shop which gets fairly warm during the summer moths and I have a metal roll up door that they were sitting next to. I figure the metal door....sun beaming on it...batteries right next to it....not good. That may have been my problem. I've since moved their location far away from the door and I've had no issues since. The batteries that puffed I just use them in low draw situations (air boat, recovery boat) or toss them.

      I make it a point to put my batteries at 3.85 if I'm not going to be using them for a few days. Makes me feel better. They come at 3.85 when I buy them also. I figure the battery manufacturers know a little more than I do about it so I follow their lead.

        Maybe I should grow up and start storing. No sarcasm intended. Maybe my junk would hold up longer. Couldn't hurt.

          Funny thing is a few of the batteries I never cared for are still going. A couple of cheap 2s batteries for my sons blackjack 9. Never even cared for those and they still going just fine. Just seems like the higher end high stung batteries are the ones that puff if I don't storage them. Or it could just be a coincidence.

            Well, you are using your batteries almost every Wednesday and Saturday/Sunday... But, I'd say you should storage mode any you are not using for a week or more and especially through the winter months.
            Research/reading I did says that storage mode and a lower temp storage location is good for a battery's overall life.
            Have fun with that....

              I allways put in storage as well. I saw a degradation chart somewhere that showed faster damage over a shorter lenth of time with higher charges. Sleep a lil easier knowing Im not storing c4. I also keep my packs on a 3' x 2' granite slab. Working on a storage cabinet made from a 440 volt service panel that I will put the granite in the bottom of.

                Ok, I read a lot of you guys saying store around 3.8 or whatever. How do you guys get it at this level? Is there a setting on ya'lls charger? I'm using a dynamite sport duo charger.

                  All my chargers have a storage mode function.

                        For example, the FMA/Revolectrix Power Lab chargers have a storage level setting. When the battery is plugged in, it will automatically either charge or discharge to 50% charge level. A worthwhile option on any charger that you purchase these days.

                          kfxguy, you already received your GO packs right? How are they coming along?

                          Thinking maybe to get some myself. Have you ever tried running smaller packs in parallel for more power?
